Security best practices for the MetaMask app

With self-custody comes responsibility. The MetaMask app provides tools to keep your assets safe, but your habits matter. Treat your seed phrase like a master key—because it is.

🔒 Back up your seed phrase offline: Write it down and store it securely, away from cameras and clouds.
🔒 Never share your secret recovery phrase: No support agent will ever ask for it.
🔒 Use biometrics and strong device security: Face/Touch ID and PINs add layers of protection.
🔒 Verify URLs and permissions: Only connect the MetaMask app to trusted dApps and double-check approvals.
🔒 Consider a hardware wallet: For large holdings, use hardware signing for extra safety.

Frequently Asked Questions about MetaMask app

Is the MetaMask app safe?

The MetaMask app is non-custodial, meaning you control your keys. It includes security features like biometric locks and supports hardware wallets. Safety ultimately depends on your practices: keep your seed phrase offline, verify dApp permissions, and never share private information.

What networks does the MetaMask app support?

It supports Ethereum and many EVM-compatible networks, including popular Layer 2s. You can also add custom networks via RPC. Always verify network details before adding them and ensure you’re on the correct chain when transacting.
